IMPROVEMENT IN HOSE-COUPLING.

To ALLWHOM 1T MAY coNcERN: v

VBe it known that I, L. J. ROBERTS, of Corry, in the county of Erie, und State of Pennsylvania, have invented a new and useful Improvernent in Hose-Coupling; and I do hereby declare the-t the following is a 'full, clear, and exact description thereof, which will'enable others skilled in the nrt to make and use the same.

reference being had te the accompanying drawings, forming part of /this specifi-cation, in which- Figure 1 is aside view of my improved hose-coupling.

Figure 2 is a vertical longitudinal sectionof the seine, taken through the line a; z, iig. 1.

Figure 3 is an end view of the same. i

`Similar letters of reference indicate like parts'. e

My invention has for its object to furnish an improved hose-coupling, so constructed and arranged that it may be quickly coupled and uncoupled, and in which the' screw-threads will be guarded from being bruised or injured; and it consists in the hoseend-and independent nut, constructed as hereinafter more fully described,

-in combination with each other end withthe other hose end.

A and B ere the hose ends and C` is the independent nut. The outer end of` the hose end A is greoved or corrugzited in the ordinary manner, for the attachment et' the hose, and it has two pins et projecting from opposite sides'for the attachment of the wrench. The upper end of the hose end A has aiscrew-thrend cut upon it, as shown lin iig. 2. Upon the inner surface of one end of the independent nut C is cut n. screw-thread, iittinginto the scre\v'thread cut upon the en'd of the hose end A. From the opposite sides ofthe nut C project. two pins e,'"or the attachment et' the wrench. VIn the opposite sid-e edges of the nut C are formed two bayonet slots for the reception ofthe pins ef the hose end D. The outer end of the hose'end B is corrugated or grooved in the ordinary manner for the attachment of the'lojse. The inner Vend of the hose end Bis made te fit into the end of the independent nut C, and has pins b projecting from its opposite sides, which enter the bayonet slots in seidnut,vas shownV in gs. 1 end'r2. D is aspring, one end of which is attached to the nut C, and the other end, which has a siightuprojeetien formed upon its lower side, rests over the outer part of the said bayonetslets, to prevent the pins b from jarring out,vshould the coupling accidentally become loosened while being transported. E is a rubber or other packing placed between the ends of the hose ends A andB, es shown in fig. 2, to form la. close joint for the coupling.

I claim :is new, und desire to secure by Letters Patent- The hose en d B, constructed with coupling-pins b', and the independent nut O, constructed with a screwthread, bayonet Aslots, and one or more springsI), in combination with each other` and with the hose end A, substnntiully as herein shown and described,` and for the purpose set forth. p
